Macy Grove Road Improvements
U- 4734 & U- 2800 Environmental Assessment 37
Fork crossing with a minimum hydraulically required bridge. Preliminary Designs were then
prepared for Alternatives 1, 2, and 5 to refine the designs in an effort to avoid/ minimize impacts
and to determine effects to the human and natural environment.
3.3 TRAFFIC CAPACITY ANALYSIS SUMMARY OF BUILD ALTERNATIVES
The following sections are summarized from the Macy Grove Road Extensions Project Traffic
Capacity Analysis Memorandum and present the traffic volumes and operational analyses,
including the evaluation of LOS for the 2030 Build Conditions and the 2035 Build Conditions.
Because the proposed extension of Macy Grove Road is less than 2 miles long, all new location
alternatives will have the same beginning and end point, and all alternatives will provide the
same access points. Traffic forecast data is considered to be the same for all new location
alternatives. Figures depicting the Annual Average Daily Traffic ( AADT) that were used in the
operational analyses for the LOS evaluations are located in Appendix B.
3.3.1 2030 BUILD CONDITIONS
The traffic forecast used for the traffic operations analyses was obtained from the Traffic
Forecasts for NCDOT STIP Project No. U- 4734 and NCDOT STIP Project No. U- 2800, Macy
Grove Road Extension and Widening, Forsyth County, North Carolina – June 2009 ( Traffic
Forecast Technical Memorandum). The traffic forecast provided AADT volumes for the
transportation network within the study area for the 2030 Build Conditions and assumed that all
improvements contained in the City of Winston- Salem MPO’s and the Greensboro Urban Area
MPO’s fiscally constrained Long- Range Transportation Plan were constructed, including the
proposed project but not the I- 74/ Airport Connector. Projected 2030 Build traffic volumes on
Macy Grove Road within the study area range from 11,800 AADT to 34,400 AADT.
For the 2030 Build Conditions, the analysis consisted of the existing and proposed roadway
network within the project study area. The project study area analysis shows that 22 of 55
analysis points will be operating at LOS E or worse in either the AM or PM peak hour ( Figure
14). During future stages of the project, the Regional Traffic Engineer will ultimately determine
whether any intersections warrant traffic signals.
It should be noted that the year 2030 is considered the build year for the Macy Grove Road
extension project, which serves additional traffic until the I- 74 Airport Connector Road project is
constructed.
3.3.2 2035 BUILD CONDITIONS
The traffic forecast provided AADT volumes for the transportation network within the study area
for the 2035 Build Conditions and assumed that all improvements contained in the City of
Winston- Salem MPO’s and the Greensboro Urban Area MPO’s fiscally constrained Long- Range
Transportation Plan were constructed, including the I- 74/ Airport Connector Road and the
proposed project. Projected 2035 Build traffic volumes on Macy Grove Road within the study
area range from 5,200 AADT to 20,800 AADT.
For the 2035 Build Conditions, the analysis consisted of the existing and proposed roadway
network within the project study area. The project study area analysis shows that 11 of 55
analysis points will be operating at LOS D or worse in either the AM or PM peak hour ( Figure
15). During future stages of the project, the Regional Traffic Engineer will ultimately determine
whether any intersections warrant traffic signals.
